sEEsAw. y,

Application led April 21, 1925. Serial No, 24,727.

To all whom, t may concern Be it known that I, ARCANGELO NATALE, asubject of the King of Italy, residing at Amsterdam, in the county ofMontgomery and State of New York, have invented certain new and usefulImprovements in Seesaws, of which the following is a specification. i

This invention relates to improvements in amusement devices forchildren, particularly to see-saws and itis the principal object of myinvention to provide a see-saw equipped adjustment of the compensatingmeans.

A still further object of the invention is the provision of a seeesawhaving elastic supports to both sides of a centrally located segmentalmain support.

These andv further objects and advantages of my invention will becomemore fully apparent as the description proceeds, and will then be morespecifically defined in the appended claim. y

In the accompanying drawing forrnmg a material part of this disclosure:

Fig. 1 is a side elevation of a see-saw constructed according to thepresent invention.

-Fig 2 is a top plan view thereof. F Fig. 3 is a cross-section on line3-3 of Fig. 4 is an end elevation of the see-saw.

The see-saw comprises a base or supporting platform 10 on end blocks 11,in the middle of which standards 12, are supported carrying at theirupper ends bearings 13 for a transverse shaft 14 having brackets15'attached thereto, which are secured to the lower face of the see-sawboard 16, proper, having upright end llanges 17 and 18, adapted to limitthe backward movement of seats 19 and 20 adapted to be moved along theand 31, respectively, attached to the outer sidewalls of the seats 19and 20, and carry at their upper ends the operating knobs 32 land 33respectively.V l

Springs 34 yand 35 are wound about the pins 26 and 27 respectively,between the upper guides 28 and 30 and collars 36 and 37 respectively,on rods 26 and 27.

To both sides of the centerv of gravity represented by parts A12, pinsl38 and 39 are attached to the lower :face of board 16, and the upperends of strong spiral springs 40 and 41 are coiled about said pins, thelower ends of which work in depressions or seats 42 and 43 formed at theupper ends of cylindrical elements 44 and 45 having foot flanges byvmeans of which they are secured on .the base 10.

The brackets 15 carry de aending segmentally shaped shoes 46 and 4grooved at the lower edge and their grooves are engaged by suitablerollers 48 and 49, connected by a shaft 50.

The operation of my device will be readily understood from the abovedescription; if the see-saw is to be used by two children of apronounced difference in their weights, the seats can be adjusted by theproper operating of the pins 26 and 27 farther away from or closer tothe central point oi" supportV of board 16 in order to ensure at alltimes the desired equilibrium of the see-saw. It is to ters Patent, is:v

In a see-saw comprising a base, standards on said base,'a shaftjournaled in said standards, a board, brackets securedto said board, apair of segmental members attached to said be understood that thedrawing showsone of e brackets, groo-ved at their lower` faces, rollersengaging said grooves, means for cushioning knobs on said pins foroperating said pins to lock said seats in their adjusted positions 10farther from or closer to they oenter ofgravity of said board to allowthe simultaneous use of 'said see-saw by children yoJf Varying Weights.

In testimony vwhereot I have aHiXed my signature; r

ARCANGELO NATALE.
